Our range of project completions for the 2013 fourth quarter remains unchanged. However, in an effort to retain more long-term project value, we have elected to keep additional solar projects on our balance sheet in the fourth quarter rather than sell them. Therefore, the mix of projects in sold versus held on our balance sheet has shifted.

In addition, due to continued market weakness, unit volumes in our semiconductor business are now expected to be below prior expectations for the fourth quarter. Pricing, however, remains approximately flat and we believe our market share remains consistent with the past several quarters.

Assuming no significant worldwide economic issues in these periods, the company now expects the following:

Forward-Looking Statements Certain matters discussed in this press release are forward-looking statements, including that for the fourth quarter of 2013, the company expects Semiconductor Materials revenue to be between $205 million and $215 million, solar energy systems sold total non-GAAP sales volume to be in the range of 209 MW to 234 MW, solar energy systems MW retained on the balance sheet to be between 100 MW and 110 MW, total solar energy systems completed to be between 309 MW and 344 MW, fully developed solar energy systems average project pricing to be between $2.75/watt and $3.50/watt, and capital spending to be between $28 million and $38 million; that for the 2013 full year, the company expects Semiconductor Materials revenue to be between $905 million and $915 million, solar energy systems sold total non-GAAP sales volume to be in the range of 380 MW to 405 MW, solar energy systems MW retained on the balance sheet to be between 125 MW and 135 MW, total energy systems completed to be between 505 MW and 540 MW, total solar energy systems average project pricing to be between $3.10/watt and $3.40/watt, capital spending to be between $130 million and $140 million, and the retained value of solar energy systems retained on the balance sheet of $1.23/watt and $123 million. Such statements involve certain risks and uncertainties that could cause actual results to differ materially from those in the forward-looking statements. Potential risks and uncertainties include concentrated project development risks related to large scale solar projects; the availability of attractive project finance and other capital for Solar Energy projects; market demand for our products and services; changes in the pricing environment for silicon wafers and polysilicon, as well as solar power systems; the availability and size of government and economic incentives to adopt solar power, including tax policy and credits and renewable portfolio standards; the ability to effectuate and realize the savings from the restructuring plan; our ability to maintain adequate liquidity and compliance with our debt covenants; the need to impair long lived assets or other intangible assets due to changes in the carrying value or realizability of such assets; the effect of any antidumping or countervailing duties imposed on photovoltaic cells and/or modules in connection with any trade complaints in the United States, Europe or elsewhere; the result of any Chinese government investigations of unfair trade practices in connection with polysilicon exported from the United States or South Korea into China; changes to accounting interpretations or accounting rules; existing or new regulations and policies governing the electric utility industry; our ability to convert solar project pipeline into completed projects in accordance with our current expectations; dependence on single and limited source suppliers; utilization of our manufacturing volume and capacity; the terms of any potential future amendments to or terminations of our long-term agreements with our solar wafer customers or any of our suppliers; general economic conditions, including interest rates; the ability of our customers to pay their debts as they become due; changes in the composition of worldwide taxable income and applicable tax laws and regulations, including our ability to utilize any net operating losses; failure of third-party subcontractors to construct and install our solar energy systems; quarterly fluctuations in our Solar Energy business; the impact of competitive products and technologies; inventory levels of our customers; supply chain difficulties or problems; interruption of production; outcome of pending and future litigation matters; good working order of our manufacturing facilities; our ability to reduce manufacturing and operating costs; assumptions underlying management's financial estimates; actions by competitors, customers and suppliers; changes in the retail industry; damage to our brand; acquisitions of pipeline in our Solar Energy segment; changes in product specifications and manufacturing processes; changes in financial market conditions; changes in foreign economic and political conditions; changes in technology; changes in currency exchange rates; the potential initial public offering of the semiconductor business and the anticipated timing of such transaction, and the expected use of the proceeds received in the separation and other risks described in the company's filings with the Securities and Exchange Commission. These forward-looking statements represent the company's judgment as of the date of this press release. The company disclaims, however, any intent or obligation to update these forward-looking statements.
